It is a version of the Ludipipo serial PIC and EEPROM programmer. It don't require a
separate power supply, but takes the power from the serial port of a PC. Connection with
the PC is made by a cable 1-1, 9pin connectors, male-female.

It is the simplest version of the Ludipipo serial PIC programmer. It don't require a
separate power supply, but takes the power from the serial port of a PC. Connection with
the PC is made by a cable 1-1, 9pin connectors, male-female.

The simplest way, how to modify Ludipipo for programming
PIC16F84A, is a parallel resistor about 8K2, which is connected to resistor 10K. The value
of parallel resistor can be reduced to 4K7, but the serial port can be demaged.

Better modification is to use an external
power supply. A circuit, which is used insted of the resistor 10K, is described in the
next picture:

p16f84_by_Sumero - schema, PCB
and layout of components of the Ludipipo modification for programming PIC16F84A.

Programmer TE-20 SEX is based on the JDM2. (Origin schematic diagram is in
jdm2.bmp.) The programmer is suitable for programing PIC16F84,
PIC16F84A a PIC16F876 (wafer cards and piccard2) in socket as well as on the board. EEPROM
24Cxx and processor 12C50x can be programmed in a socket only. (To program EEPROM on the
board Phoenix or Smartmouse must be used.)

It don't require a separate power supply, but takes the power from the serial port of a
PC. Connection with the PC is made by a cable 1-1, 9pin connectors, male-female. Some pins
of sockets must be cut before mounting.
